Astronomers have discovered a new giant molecular cloud (GMC) in the Milky Way, a finding that has expanded our understanding of the galaxy’s structure and star formation processes. This new cloud, ...

Starquakes in stars from cluster M67 reveal hidden pauses that mark major internal changes. These pauses improve how we estimate star ages.

The CMZ is a region of clouds rich in dust and molecular gas that roils around the galactic nucleus. It measures up to 2,000 ...

Fluffy strands of cosmic gas and dust illuminated by bright young stars form a beautiful cloudscape in a neighboring nebula.

The smallest disk identified, meanwhile, stretched to just 0.6 AU – closer to the star than the Earth is to the Sun.

New experiments on thallium decay have helped determine the Sun formed over 10–20 million years, improving stellar ...

Learn more about the songs of the stars, which tell of the transformation of our galaxy over time.

As a star ages and its mass and internal structure change—such as when a star evolves into a subgiant or red giant—these ...

This type of cluster typically contains a few dozen to a few thousand relatively young stars from the same giant molecular cloud. In this case, NGC 460 is believed to have formed following a ...

A team of astronomers at the National Radio Astronomy Observatory (NRAO) discovered the cloud at the midpoint of a dust lane within the Milky Way’s central bar, approximately 23,000 light-years away.

A team of researchers used the James Webb Space Telescope to uncover new details about SIMP 0136, a free-floating planet in ...
